Moving Enhancements to be a direct subdirectory of $UserBaseDirectory 
did NOT work for me!  Neither

   <<Enhancements`RootSearch`

nor

   <<RootSearch`

find RootSearch.m.

One thing that does work is to move Enhancements to be a subdirectory of 
ToFileName[{$UserBaseDirectory, "Applications"}].

But what I was hoping for was some way of setting some environment 
variable, e.g., so that Mathematica would search subdirectories of 
$UserBaseDirectory other than just Applications and its subdirectories.
